Abstract: A process is provided for producing a stable fabric comprising: 1) providing a first fabric formed from reinforcing fibers, 2) providing a nonwoven web produced from fibers, having softening temperature lower than said reinforcing fibers, on at least 1`one side of said first fabric to form a structure, 3) heating said structure to a temperature between the softening temperature and melting temperature of said nonwoven web, and 4) cooling said structure to thereby provide a stable two-dimensional fabric. In a preferred embodiment, the structure of step 2) is put into a mold prior to heating step 3), heating said structure in the mold according to step 3), cooling said structure in the mold according to step 4) and thereby providing a three-dimensional shaped article. A product is also provided produced by these processes. [FIGURE 1]
We Claim:
1. A process for producing a stable fabric designed for the production of shaped articles comprising: 1) providing a first fabric formed from reinforcing fibers, 2) providing at least one nonwoven web produced from fibers having a softening temperature lower than the softening temperature of the reinforcing fibers, on at least one side of said first fabric to form a structure, 3) heating said structure to a temperature between the softening temperature and melting temperature of the fibers comprising said nonwoven web, and 5) cooling said structure to thereby provide a stable two-dimensional fabric.
2. The process of claim 1 wherein the structure of step 2) is put into a mold prior to heating step 3), heating said structure in the mold according to step 3), placing into a mold while hot, then cooling said structure in the mold according to step 5) and thereby providing a three-dimensional shaped article.
3. The process of claim 2 wherein the nonwoven web is formed from thermoplastic fibers.
4. The process of claim 3 wherein the thermoplastic fiber is a polyamide or co-polyamide.
5. The process of claim 3 wherein the elastic thermoplastic fiber is a polyolefin or co-polyolefin, polyurethane, polyester, or co-polyester.
6. The process of claim 1 wherein the reinforcing fibers are selected from the group consisting of carbon fibers, ceramic fibers and poly alpha-aramid fibers.
7. A process for producing a stable three-dimensional fabric comprising : 1) providing a first fabric formed from reinforcing fibers, 2) providing at least one nonwoven web formed from fibers, having a softening point lower than said reinforcing fibers, on at least one side of said first fabric to form a structure, 4) placing said structure of step 3 in a mold, 5) heating said structure in said mold to a temperature between the softening temperature and melting temperature of said nonwoven web, and 5) cooling said structure in said mold, 6) removing said structure from said mold to thereby provide a stable three-dimensional fabric.
8. The process of claim 7 wherein the nonwoven web is formed from thermoplastic fibers.
9.The process of claim 7 wherein the thermoplastic fiber is a polyamide or co-polyamide.
10.The process of claim 7 wherein the reinforcing fibers are selected from the group consisting of carbon fibers, ceramic fibers and poly alpha-aramid fibers.
11.The process of claim 7 wherein the elastic thermoplastic fiber is a polyolefin or co-polyolefin, polyurethane, polyester, or co-polyester.
12.The process of claim 7 wherein the reinforcing fibers are selected from the group consisting of carbon fibers, ceramic fibers and poly alpha-aramid fibers.
13.The product of the process of claim 1.
14.The product of the process of claim 7.
