FOAM LAMINATE PRODUCT AND PROCESS FOR PRODUCTION THEREOF |
摘要 |
<p>A laminate product comprising a foam core having a pair of opposed major surfaces and a cover layer secured with respect to each major surface is described. The cover layer is essentially free of fibreglass and comprises a polymeric substrate having disposed therein a plurality of porous material layers. It has been found that the use of fibreglass as a reinforcing material (and other sheet materials having a tensile modulus of greater than or equal to about 0.5 GPa when measured pursuant to ASTM D 5034) in a foam laminate product can be avoided by using a porous material layer in place of the fibreglass. In a preferred embodiment of the invention, the porous material layer has a tensile modulus less than that of fibreglass mat yet can be used to produce a foam laminate product having significantly higher strength properties.</p> |
