In this case, you may add this code in function.php file of your child theme:
add_action('woocommerce_single_product_summary', 'et_print_brands', 10);
function et_print_brands(){
global $post, $product;
$terms = wp_get_post_terms( $post->ID, 'brand' );
if(count($terms)>0) {
?>
<p>Brands:
<?php
foreach($terms as $brand) {
$image = '';
$thumbnail_id = absint( get_woocommerce_term_meta( $brand->term_id, 'thumbnail_id', true ) );
?>
<a href="<?php echo get_term_link($brand); ?>">
<?php
echo $brand->name;
?>
</a>
<?php
}
?>
</p>
<?php
}
}
